Bulldozer isn't due out until later this year but we can now give you the beginnings of an answer: yes, no and maybe.

If that sounds like a non-answer, bear with us. Bulldozer promises to be the most revolutionary CPU architecture in living memory. Its design fundamentally challenges the very concept of a CPU core. Even with full architectural disclosure, estimating performance is tricky, bordering on impossible. However, intentionally or otherwise, AMD has let slip a few metrics which can help piece together a picture of performance.

Yesterday's Verizon iPhone launch wasn't particularly exciting for the rest of the world, but one glimmer of interest has emerged: Personal Hotspot functionality may be coming to all iPhones in the iOS 4.3 update.

The Verizon iPhone 4 allows users to make their iPhone a Wi-Fi hotspot for up to five separate devices to use to connect to the internet.

Speculation has since abounded that all iPhones will eventually get this feature, with Boy Genius Report seemingly confirming the rumour via a source who claims that it will be included in the update to iOS 4.3.

There's been a fair amount of confusion around the web over the license of applications bought from the Mac App Store, with some people claiming that you can't use the apps for any kind of commercial purpose.

Check forums where Mac users congregate, and you'll find this repeated whenever discussing the Mac App Store. And, as often happens, some people have got very heated about this indeed, claiming that store is "useless" or "brain dead" because of it.

Discs are so yesterday. They get damaged, they get lost, they won't work with all your equipment and they need a player in every room.

For a long time, moving a whole media collection onto a central server has been the dream of many. But potential problems, including the inevitable mess of cables, complex switch configuration and living with a noisy PC next to the telly, have put some people off.

Forget all that negativity. It's now possible to build a discreet, powerful system that will neither cost the Earth, nor need your family's approval for cable tethering. Best of all, you won't need to make compromises for quality.

The cat's out of the bag: the much-rumoured PSP2 not only exists, but its official unveiling is a matter of weeks away.

With the PSP Phone expected to turn up at February's Mobile World Congress 2011 it's going to be a big couple of weeks for Sony, and if the PSP2 is as good as rumours suggest then it could wipe the smile off Nintendo's three-dimensional face.

It was a good CES for Intel. Sandy Bridge is out and the performance is ace. Our reviewer Jeremy Laird calls the new Core i5 a "huge leap forwards".

But it was a great CES for ARM. The Cambridge-based company didn't even need to do anything. Microsoft came to them.

Microsoft's announcement- while not a complete surprise - means we'll see next-gen tablet devices and even more efficient netbooks running undefined Windows-based operating systems on ARM-based SoC silicon as well as that of Intel and AMD.

Just because we can do something doesn't mean we should. Before this wisdom dawned on the Linux community, Red Hat, Debian and Slackware had spawned several dozen distros. Some died a single-release death, but a lot survived and a vibrant community grew around them.

That, along with all the distros designed to meet specific needs, means there's a lot of variety in the Linux world. While community is key to a good desktop distro, it also needs thorough documentation on wikis and blogs, and ample support.

In addition to community-based channels, such as mailing lists, user forums and IRC, some distros also offer more traditional paid-for support packages.

The Nokia X3 Touch and Type is not to be confused with the Nokia X3, a music-friendly handset that we reviewed early in 2010. Rather strangely, Nokia has a multiple nomenclature for its handsets these days

Combined with the relatively new interface and shiny outer-skin Kingston is charging almost £200 for this 120GB hard drive. But then this flash memory-based drive has the performance to almost justify it.
